Abstract

The embodiment of the invention provides a state data compression method and device for mechanical equipment and the mechanical equipment and belongs to the field of the mechanical equipment. The method comprises the steps of collecting N pieces of same class of state data of the mechanical equipment in a time period; determining a motion state of the mechanical equipment according to the N piecesof same class of state data; and carrying out data compression according to the motion state of the mechanical equipment, thereby obtaining compressed data. According to the method, the device and the mechanical equipment, targeted efficient compression can be carried out for the state data of different motion states of the mechanical equipment, so data transmission and storage are facilitated.

Description

technical field [0001] The invention relates to mechanical equipment, in particular to a state data compression method and device of the mechanical equipment and the mechanical equipment. Background technique [0002] The current data compression is mainly divided into the following types: downsampling compression method, piecewise linear interpolation method, vector quantization method and signal transformation method, downsampling method for data compression, fixed compression ratio, simple algorithm; piecewise linear interpolation method When compressing waveform signals, the compression ratio is high and the speed is fast; the vector quantization method and signal transformation method have high compression ratio and good waveform characteristics preservation, and are mostly used in the processing of complex process data without real-time requirements such as radar and seismic survey. However, none of the above compression methods can perform compression well on mechanic...
